Abstract

A multilayer film including a first outermost layer comprising nylon, a first adhesive layer, one or more core layers comprising one or more polyolefins, a second adhesive layer, and a final outermost layer comprising nylon.

Claims (41)

1 . A multilayer film comprising:

a first outermost layer consisting of nylon;

a first adhesive layer;

at least one core layer comprising at least one polyolefin;

a second adhesive layer;

a final outermost layer consisting of nylon;

wherein the first adhesive layer is disposed between the first outermost layer and the at least one core layer; and

wherein the second adhesive layer is disposed between the final outermost layer and the at least one core layer.

2 . The multilayer film of claim 1 , wherein the first outermost layer and the final outermost layer each comprise approximately 100% of the same nylon.

3 . The multilayer film of claim 1 , wherein the first outermost layer comprises approximately 100% (wt.) of a first nylon and the final outermost layer comprises approximately 100% (wt.) of a second nylon.

4 . The multilayer film of claim 1 , wherein the first outermost layer and the final outermost layers are nylon 4,6, nylon 6, nylon 6,6, nylon 6,9, nylon 6,10, nylon 6,12, nylon 6/12, nylon 6/66, nylon 66/6, nylon 11, nylon 12 or mixtures thereof.

5 . The multilayer film of claim 1 , wherein the first adhesive layer and the second adhesive layer comprise a linear low-density polyethylene (LLDPE) resin.

6 . The multilayer film of claim 1 , wherein the at least one core layer comprises a high density polyethylene (HDPE).

7 . The multilayer film of claim 1 , wherein the at least one core layer comprises at least four layers and each of the at least four layers comprises a blend of a linear low-density polyethylene (LLDPE) and a low-density polyethylene (LDPE).

8 . The multilayer film of claim 7 , wherein each of the at least four polyolefin layers comprises approximately 75% (wt.) of a linear low-density polyethylene (LLDPE) and approximately 25% (wt.) of a low-density polyethylene (LDPE).

9 . The multilayer film of claim 1 , wherein the first outermost layer is approximately 10-20% of the total thickness of the multilayered film;

wherein the first adhesive layer is approximately 1-10% of the total thickness of the multilayered film;

wherein the at least one core layer is approximately 55-65% of the total thickness of the multilayered film;

wherein the second adhesive layer is approximately 1-10% of the total thickness of the multilayered film; and

wherein the final outermost layer is approximately 10-20% of the total thickness of the multilayered film.

10 . A multilayer film comprising:

a first outermost layer comprising approximately 100% of a 6/66 nylon;

a first adhesive layer;

at least one core layer comprising at least one polyolefin;

a second adhesive layer;

a final outermost layer comprising a nylon 6/66 blended with a nylon 6;

wherein the first adhesive layer is disposed between the first outermost layer and the at least one core layer; and

wherein the second adhesive layer is disposed between the final outermost layer and the at least one core layer.

11 . The multilayer film of claim 10 , wherein the final outermost layer comprising a nylon blend consists of at least approximately 90-98% (wt.) of a 6/66 nylon and at least approximately 2-10% (wt.) of a nylon 6.

12 . The multilayer film of claim 10 , wherein the at least one core layer further comprises at least one layer comprising approximately 60-85% (wt.) of a linear low-density polyethylene (LLDPE) and approximately 15-40% (wt.) of a low-density polyethylene (LDPE).

13 . The multilayer film of claim 10 , wherein the at least one core layer consists of four layers, wherein each of the four layers comprises approximately 60-85% (wt.) of a linear low-density polyethylene (LLDPE) and approximately 15-40% (wt.) of a low-density polyethylene (LDPE).

14 . A multilayer film comprising:

a first outermost layer comprising approximately 100% of a type 6 nylon;

a first adhesive layer;

at least one core layer comprising at least one polyolefin;

a second adhesive layer;

a final outermost layer comprising approximately 100% of a 6/66 nylon;

wherein the first adhesive layer is disposed between the first outermost layer and the at least one core layer; and

wherein the second adhesive layer is disposed between the final outermost layer and the at least one core layer.

15 . The multilayer film of claim 14 , wherein the at least one core layer further comprises at least one layer comprising approximately 60-85% (wt.) of a linear low-density polyethylene (LLDPE) and approximately 15-40% (wt.) of a low-density polyethylene (LDPE).

16 . The multilayer film of claim 14 , wherein the at least one core layer consists of four layers, wherein each of the four layers comprises approximately 60-85% (wt.) of a linear low-density polyethylene (LLDPE) and approximately 15-40% (wt.) of a low-density polyethylene (LDPE).
